LIQUID-COOLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 261,453, dated July 18, 1882. Application sied Decemter 31, 1881. (No model.)

To all whom 'it may concern:

Be it known that I, GEORGE C. HoDGDoN, a citizen of the'United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented'certain new useful Improvements in Apparatus foi" 0001-. ing Liquids, of which the following is a specication, reference being had therein to the accompany-ing drawings. A

My inventiourelates to an improvement in 'apparatus for cooling liquids in a refrigerator;

and it consists in the introduction of a at coil of ymetal pipe in the bottom of the ice-pan of the refrigerator, which coil, containing the liquid to be cooled, is connected with an in duction and an eduction pipe, the former attached to the reservoir furnishing the liquid, the latter for drawing the liquid ,from the coil, as will be fully described hereinafter.

It has heretofore been the custom to place.

vessels containing the liquids to be cooled near orin contact'with theicein theice-chamber of the refrigerator. There areinconveniences connected with this, since there is' frequently a want of space for pitchers or other vessels to be placed, and when greater quantities of cooled liquids are needed the room required for the vessels containing them is entirely too limited. vThe frequent opening and shutting of the ice-chamber for removing vessels or placing them inside is also an objection, for the temperature lwithin i the refrigerator is raised whenever the door is opened. Others have introduced pans for holding the liquid to be cooled, placing them under the ice-tray.; but this also is found objectionable on account of the necessarily limited space in the pans to contain the liquids, andalso on account of lthe loss of carbonicacid gas from fermented beverages, that unavoidably occurs during the transfer from casks or other vessels to the pans. There is also the danger of bursting such pans by pressure of the water when connected with hydrants or main watersupply of the house. Again, others have introduced pipes standing around the sides of the ice-chamber; but in this arrangement the cooling effect of the ice is very slow and the pipes are in danger of being injured by the sharp corners of the ice falling against them.

My object has been` to furnish an apparatus by which an unlimited quantity of water or other liquids can be Vcooled without opening the door of the refrigerator or in any manner interfering with its interior, and at the same time so arrange it as to occupy the least possible space, easily to be removed when required, and fully protected from injury of the ice. This is attained by connecting an induction-pipe directly with the reservoir that furnishes the water or other liquid, without first exposing it tothe atmosphere, and leading it into a horizontal or flat coilof pipe of considerable length, through which the liquid has to flow, constantly exposed to the cooling inlinlence of the ice, so that its temperatureis gradually reduced on its passage to the outlet.

Figure 1 is a horizontal section taken -through the upper portion of the frame of the supplies the liquid to be cooled. The outer end ot' the coil is coupled with an eductionpipe, e, that terminates in a faucet outside of the refrigerator. The couplings between the coil vand the pipes b and e are removable `by hand to allow the removal of the coil and pan for repairs or other purposes. On the coil b is laid a thin perforated sheet of metal, f, and Y on this the ice is placed; or the coil may be brought in immediate contact with the ice without an intervening sheet; but the former is preferable, owing to the protection it offers tothe coil when the ice is put on. It is not ind-,ispensably necessary to form .a coil of the pipe, for it maybe laid flat side by side in parallel lines until the space assigned to it be filled; but for greater convenience and cheapness the coil form is preferred.

Having thus described 'my invention, I

claim- In a refrigerator, the combination of au ieechamber, A, provided with an icepan, a, the pipe b, connected at its inner end to a supplysonrce for the liquid and provided with a cook at: its outer end, and the perforated plate f, 1o placed on the top of the pipe, substantially as shown.

1n testimony whereof l have axed my signature in presence of' two Witnesses.
